i have been carrying my 40c in an old faithful holster...
Quick-Assemble-Kit - Inside the Waistband - Hip - Gun Holster Kit - Old Faithful Holsters but in an owb. it is designed to be worn around the 4 o'clock position and is as comfortable as you can get. i can hardly tell the gun is even there. the only difference i would make if choosing another holster would be to get their iwb, instead of the owb. the flexible leather on the skin has to feel much better than the rigid kydex.
